      Description

      OCI_HTYPE_TRANS, 0, 0); 

      QOCIDriver::open function using local variable OCITrans* trans;

      r = OCIHandleAlloc(d->env, reinterpret_cast<void **>(&d->trans), OCI_HTYPE_TRANS, 0, 0); 
      

      but never get released. 

      In an application that running threads with open/close connection to DB a memory leak can be observed. 

      Solution: 

      treat OCITrans* trans in the same way as the *env variable.

      Put it in the QOCIDriverPrivate section and release it while closing connection.
